Abstract

In this modern era, students' interest in using bicycles as a means of transportation is decreasing due to various factors, such as traffic congestion, limited storage facilities, and parking security risks. To overcome these problems and encourage the use of bicycles as a more environmentally friendly means of transportation, innovative solutions are needed. Smart Bike Parking Station was developed to improve the safety and comfort of bicycle parking, especially in the campus environment. The Smart Bike Parking Station application utilizes Firebase as a database to store user information and manage the parking system. The login process uses Firebase Authentication, while data from the parking sensor is monitored through the Firebase Realtime Database. This system is also equipped with RFID technology for access control, ensuring that only registered bicycles can enter and exit the parking area. In addition, this application allows monitoring of the number of parking slots in real time and provides automatic notifications to users in the event of a theft attempt. The implementation of this system is supported by hardware such as an ESP32 microcontroller, vibration sensor, buzzer, motor driver, LED, and LCD, all of which are connected through an IoT platform with Google Firebase. Quality of Service (QoS) testing of the internet network used showed an average throughput of 7.24 Kbps, packet loss of 0%, an average delay of 346 ms, and an average jitter of 346 ms. With this system, it is hoped that more students will switch to using bicycles to go to campus, so that they can reduce the use of motorized vehicles and support efforts to reduce air pollution.

Abstract

Fertilizer plays a crucial role in maintaining soil fertility and supporting optimal plant growth. However, fertilizer quality monitoring in previous studies has generally been conducted partially using separate tools and has not been integrated with an application-based real-time monitoring system, resulting in inefficiency and poor decision-making. This study aims to design and implement an integrated Android-based fertilizer quality monitoring system for planting media. The methods used include hardware design using a 7-in-1 soil sensor and an ESP32 microcontroller, Android-based software development, and data integration using the Firebase Realtime Database for real-time communication. System testing was conducted by measuring temperature, humidity, pH, and the content of Nitrogen (N), Phosphorus (P), and Potassium (K) in the planting media. The test results show that this system is capable of measuring parameters with a temperature value of 26.2°-28.7°C, humidity 25.3-29.1%, pH 6.2-7.1, nitrogen 107-250 ppm, phosphorus 280-478 ppm, and potassium 265-492 ppm in real-time. In addition, this system is equipped with an automatic fertilizer condition classification feature as well as plant recommendations and care suggestions. The main contribution of this research is the development of an Android-based fertilizer quality monitoring system that is integrated, real-time, and capable of increasing monitoring efficiency and supporting decision-making in sustainable planting media management.

Abstract

Perkembangan teknologi Internet of Things (IoT) telah mendorong berbagai inovasi dalam pemantauan lingkungan secara real-time. Namun, implementasi teknologi tersebut dalam pembelajaran di sekolah kejuruan masih terbatas karena kurangnya perangkat praktikum yang aplikatif dan kontekstual. Kondisi ini juga ditemukan pada siswa SMK Citra Negara yang belum memiliki pengalaman langsung dalam memanfaatkan teknologi IoT untuk pemantauan kualitas lingkungan. Oleh karena itu, kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengembangkan dan mengimplementasikan training kit berbasis IoT sebagai media pembelajaran dalam monitoring kualitas limbah cair bagi siswa SMK. Mitra kegiatan adalah siswa SMK Citra Negara. Kegiatan dilaksanakan melalui beberapa tahapan, yaitu tahap persiapan, tahap pelatihan, tahap implementasi, serta tahap evaluasi untuk menilai efektivitas program. Sistem monitoring yang dikembangkan memanfaatkan beberapa sensor, antara lain sensor suhu dan kelembapan (DHT22), sensor kekeruhan air (TS-300B), sensor gas amonia (MQ-135), sensor gas LPG (MQ-5), serta sensor pH (pH-4502C) yang mampu mengirimkan data secara real-time. Hasil kegiatan menunjukkan bahwa siswa memperoleh pemahaman yang lebih baik mengenai konsep Internet of Things dan penerapannya dalam pemantauan kualitas limbah cair. Training kit yang dikembangkan mampu menampilkan serta mengirimkan data secara real-time melalui aplikasi, sehingga memberikan pengalaman belajar yang praktis dan aplikatif bagi siswa. Dengan demikian, pemanfaatan IoT dalam monitoring limbah cair dapat menjadi media pembelajaran inovatif yang mendukung penguatan kompetensi teknologi siswa SMK sekaligus meningkatkan kesadaran terhadap pengelolaan lingkungan berbasis teknologi.
